INTRODUCTORY ESSAY. 257
The Alpine vegetation is also a mixture of European, Si-
berian (and Tibetan), Oriental,, and Himalayan species, with
little or 110 peculiarity.
As instances of the Himalayan flora advancing westward
beyond the Indus, we may mention the following natives of
Afghanistan,, none of which have hitherto been detected in
BerberLs Asiatica. Lonicerse, several.
Clematis grata. Impatiens, sp.
Thalictrum pedunciilatwn. JEseulus.
Corydalis Mborcroftiana. Sarcococca primifomnis*
Edgeworthia. Cedrus Deodara.
Dalbergia Sissoo (cult. ?) Pinus longifolia.
Mazus ruyosits ? „ Gerardiana.
Adhatoda Vasica. „ excelsa.
Myrsine, sp. Abies SmitJiiana.
The following have not, so far as we are aware, been found
east of the Indus, nor in any part of British India:—
Delphinium* eamptocarpwu. Hypecoum jprocwniben*.
Leontice Leontopodium. Bosa, rubigmosa*
Bongardia Hawivolfii. Amygdolusfwrcatus?
Glauciuni elegans* Ephedra ciliata.
„ corniculatvm. Chamserops Ititcliieana.
Bcerneria fiylrlda, ^Egilop&, &e-\ era! species ?
Our knowledge of the botany of this province is principally
due to the labours of Griffith and Stocks. Mr. Griffith ac-
companied the army which marched in 1838-39 from Sind,
through Quetta and Candahar to Ghazni and Kabul* Prom
Kabul he crossed the chain of the Hindu Kush to Bamian
and Singhan, and spent some time in the Kuner valley. His
collections, though formed under circumstances of great diffi-
culty, are very good, amounting probably to about 1000 spe-
cies. Dr. Stocks twice visited Beluchistan and the southern
parts of Afghanistan, penetrating as far as Quetta at con-
siderable personal hazard. Some other collections were made
while tue country was occupied by the British army^ but we
